SEAL-PRESS.

SPECIFICATION forming part of Letters Patent No. 326,897, dated September 22, 1885.

Appllcatlon'dlcd February 18, 1885. (No modelJ i To tl whom it may concern:

Re it known that l, EDWARD .'l. BRO-ons, a. citizen ol' the Unit-ed States, residing st East Orange, in the State of New Jersey, hai-'e invented a new and useful Improvement. in Scal- Presses,(1tatcliet-Die,) of lwhich the following is n. specification.

This invention relates to improvements ou my ratchet seal-press for thoroughly compressing or punching and ntamping'all those seals which are so fastened or secu red, mtented lll'ay 1384, Uni ted States Patent No. 22,284.)

The present invention consists in certain novel combinations of parts, hereinafter described and claimed. .lts objects are, first, tn insure fully pressing cach seal without lnving to reverse thenmtion ofthe die-advancing cani, and at the same timo to facilitate carrying and applying the preferred form of press by rendering its lever-handles normally closed together and iis dies normally separated or open;- secondly, to provide l'or pressing each seal by more than one movement of the actuating lever-handle without permitting incompleto pressing operations; thirdly, to provide lor scvcralpressing operai-ions du ring one,

rotation of the cam, and by the same means t-o quiclclreach pressing operation and distribute wear, so as to increase the life of the press; fonrthly, to equalize strain on the parts, and at the same time aid in preventing fraudulent manipulation ol' the press, and,

iflhiy, to provide a die-press having a pair of lever-handles substantially in line with the dies,` and normally closed together with a hammer-face in such amanner as to brace the head. of the press and resist the bursting strain within its mouth at each pressing opera-tion. A sheet ot' drawingstshowing this invention embodied in a scalpress having a pair of dies,

. as aforesaid, accompanies this specification as part thereof.

Figure 1 of these drawi'ngs is a side view ofl Fig. 2 is the seal-press in normal condition. a sectional side view thereof, showing its movable parts in dillerent positions by full and dottcdlines, so as t-oillustrate the pressingcross-section on the liue 4 4, Fig. 2. Fig. 5 is operation. Fig. 3 is an edge view'ol'the die end ol' the press, partly in longitudinal section on the lino 3 3, Fig. 2. Fig. -L1epresents a full and dotted lines the full a side view on a smaller scale, illustrating by stroke ofthe die`l actuating lever-handle. Like letters of reference indicate the same 55 parts in all the ligurcs.

The external paris of this ratchet-movement die-press are formed by two light castings, preferably of malleable iron, one comprising a rigid lever-handle, H, a recessed body, B, 6o and a recessed head, H', while the other forms the movable lever-hamlle Il, with a recessed body part, B, which fils within said body B. J A. strng pivot-pin, P, unites the two eastings, extending forthis purpose through the Side walls of said .body B andsaidbody part Bandforms the center upon which the mow able handle H oscillates; and upon thispin, within said body part l, a rotary cam,v (l, isl loosely mounted, the sinne having preferablyl 7o four wings, marked, respectively, a, b, c, and d in Fig. 2,) cach terminating in a deep shoulder, which is radial, or substantially radial, to thc pin. A pair ol' ratchet-wheels, R lt", rigidi y united with the respective ends or sides 7 5 of the rotary cam C, are acted on by working- 'pawls W W, Figs. 2 and 3, which are pivotod by a piu,l", parallel with said pin l Within said body part ll, so as to move with said movable handle ll, and'are provided with 8o tail-springs, which hear against solid portions of said body part,.as shown in Fig. 2. Said pawls are kept apart by a Washer-sleeve, XV',

on the pin I, and'ivork independently of each other, but simultaneously, if all the partsare i n working condition. A pair ol'detent-pawls, XX', Figs. 2 and 4, in mesh with the respeptivc,ra.tchctwbcels, and each'having a.- tailsprlng, are pivoted on a third pin, P, paralle! with the others within the body B, so as 9o to bestationary relatively to said pawls W W.

A pair of dies, D D1, respectively sliding and fixed, occupy cylindrical bores in line4` with each other, extending inward through the head Hand'body'B to the cavity ofthe 95 latter, and separated by the sealadi11iti'.ing mouth M, within which theinner or face endsi of the dies are located. ,.lhe inner end, e, Figs. 2 and 3, of the sliding dieDis so shaped as to eoact properly with the wings a b c d of zoo said cam C, and between this end audits face end a contracted and slotted shank, a., is s' formed to receive a. Spital spring, S, and an abut luent-pin, l", which provide Tor relmcling the die l) as soo'n as itis released hy the cam (i at the end of each pressing operation. A rctracting-Spring 'may be applied instead ill the manner represented at s ill said patent of May ti, 18H-t.

' "he head il' is further constrlieled with a hammer-filer, h, formed hy a project-ion dianletrieally opposite the mont-h M, no that the loller may iw largeand unobstructed 'ls represented, and at the salue-.tinte the strani within the lllonth at each ...pressing operation is snesim-ly on the innert-nd, c, of tllesliding die 1),

in the manner re )resented in Fin'. 2 and; ow-

ing to their lnultiplieity, wear is distributed, and its ell'eet thus reduced, as aforesaid, while with four Wings, each corresponding in effective movement with the fnll stroke of the movable lei-'erdlandle ll", as represented ill Fig. I, eachprl-.ssing operation may be colnpleled by a. single movement of said handle.

llnll strokes of the lover-handle 1l may bc insured by known pawl-andfratehetdevicessneh, for example, as the one shownf in said patent ol' May (i, lSSl-so that the earn C shall always stop ill proper position for the succeeding,r operation; but apart fronl the latlerit isadvantllgeous that sealels be permitted to nnlke more than one stroke of the handle, so as to use the latter in the position most eonveniont to each. fnl this is provided fol' in nly presentseal-press, :lsshoivn ill the drawings, wit-hoot ptlrlnitting incomplete pressing operations, :Ls aforesaid, owingr to the collation of the level-handle il"I njith its body part B2, the working-panda 'W W, mlchet-wheels Rl R, deient-pawls X, winged eaux C, and die l), as already lflescrilnid. Referring to Fig. 2, it will be seen that by oscillating said handle Uit-he r-.aln C may llc turned a great-er or less distance at ellell stroke, but only forward, and the seal cannot be released by retracting,r the diel i) or pernlittiln,Y it lo rect-de until said ealn hasl turned forward to ille position in which itisrepreslnted bydotl-ed lines in Fig. 2, or a norrespoluling position, ill

for exalnl'ilc-lnnst pas# behind ille die en l c, thus fully pressing the seal that is ill the nloulh M.

As soon :is :l .sl-:ll is fully pressed it is illsiautalwously released by the rt-.traetiolloftllo die l) by said spring S, the radial shoulders of the cani C permitting auch retraction, and if the pressing was done by a fnll stroke of the lever-handlel IU, or one toot-ll ot' each ratchet-wheel at a time, the handles are closed at its elld, :is represented in Fig. 1, and ill dotti-.d lilies in Figs. 2 and 5, and the. dies are left'fully open, really to receive the next seal between them, as shown in Figs. l'. and 5, and in dot-ted lilies invFig. 2.

Should thecluu f." become disarrangl'ld with reference tu the lcverflnlndle il by incompleto strokes, leaving the handles separa-ted at the end of the pressing operation, itis only neeessaryto close the handles and then oseillate. said handle llI with short strokenso astotnrn the ralehetwheels one toothatatilllt-,\lntiltlle die l) is again retracted bythespringSmhiell action can he heard. The press is then ready for use again.

Should dust eet into the chamber within the body li and body part ll"`, it may bo shook ont through all openin'f, o, ll`igs. .5 and 4 ill the lat-ler, or the parts' lay llo rendered dustlight hy making said body and body part more nearly circular, and extending concentric solid port-ions of each` so as Lo mask the openings in the other.
